JOHN W. STEVENSON, OF ST. LOUIS, MISSOURI, ASSIGNOR TO PERLEY A. GRISWOLD, OF ST. LOUIS, MISSOURI.

I-IYDRANT.

To all whom 'it may concern:

Be it known that I, JOHN W. STEvENsoN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Hydrants, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof, in which Figure 1 is a longitudinal sectional viewthrough a hydrant embodying my invention, the same being passed horizontally through the wall of a building or the like, a hose being shown coupled to the hydrant and the valve of the hydrant being open; Fig. 2 is a longitudinal sectionalview through the hydrant, showing the Valve closed and a cap on the outer end of the hydrant; Fig. 3 is an enlarged sectional view taken approximately on the line 3 3, Fig. 1; Fig. 4 is a perspective View of the coupling and valveopening member; Fig. 5 is a perspective view of the outer end portion of the hydrant tube; Fig. 6 is a perspective view of the outer portion of the valve-stem; and Fig. 7 is a view, partly in elevation and partly in section, showing a slightly modified form of my hydrant.

This invention relates to a new and useful improvement in hydrants, the object being to provide a simple, durable and inexpensive hydrant which is easily operated and which may be put to many advantageous uses.

With this object in view, my invention consists in the novel construction of the several parts of my hydrant and in the novel arrangement and combination of the same, all as will hereinafter be described and afterward pointed out in the claims.

As shown in the drawings, my hydrant comprises a tubular member 1, which is adapted to be connected at one end by a coupling-member 2 to a water-pressure and supply-pipe 3. At the inlet end of said tubular member 1, the bore 4 thereof is slightly enlarged, as at 5, to accommodate a valve 6 preferably of rubber or other suitable material. This valve 6 is mounted on a rod or stem 7 and is adapted to coperate with a .seat 8 at the inlet end of bore 4, as shown clearly in Figs. 1 and 2. The rod 7, which extends through bore 4 of member 1, is adapted' to be held centered therein by cross-pins 9 arranged diametrically Speecation of Letters Patent.

through said rod substantially at right angles to one another. By this arrangement, by means of the pressure of the water entering the inlet end of member 1, the valve 6 will be held to its seat, thereby closing bore 4. At the outer end of stem 7 is a cross-piece 10 secured thereon by a screw 11, the ends of this cross-piece 10 being adapted to bear against a shoulder 12 formed by counter-boring the outlet-end of member 1, as at 13, see particularly Figs. 1 and 2, to limitthe inward movement of stem 7 when the valve is being opened, as more fully hereinafter appearing, the outer end of the stem 7 normally projecting a slight distance beyond the shoulder 12 when the valve is closed.

Fitting in the counter-bore 13 of member 1 and resting against said shoulder 12 is a washer 14, which is adapted to coperate with the inner end of a coupling and valveopening member 15 to make a water-tight joint when said member 15 is inserted into said member 1 to open said valve. This member 15 is provided with a tubular nipple portion 16, which is provided with oppositely-disposed lugs 17 adapted to coperate with screw-threads 18 provided therefor in said counter-bored portion 13 of the tubular member 1. At diametrically opposite points the screw-threads 18 are cut away, as at 19, to permit of the insertion of the lugs 17 endwise of the member 1 before the same are turned into the said threads. The lugs 17 on nipple 16 are preferably staggered to correspond with the pitch of threads 18; if desired, however, said lugs may be arranged diametrically opposite and the threads 18 may be oppositely-disposed halfthreads to coperate therewith. The intermediate outer periphery of member 15 is enlarged and preferably knurled or otherwise suitably roughened, as at 20, see particularly Fig. 4, to provide for the easy turning of the said member, and the periphery of the outer end portion of said member 15 may be suitably threaded, as at 21, or otherwise arranged or formed to receive the end of a hose or other pipe 22.

Extending diametrically across the end of the bore of nipple 16 is a bar 23, which is adapted to bear against the end of the valvestem 7 when the member 15 is screwed into position in the member 1 and thereby move the valve-stem 7 inwardly and unseat the valve 6 against the pressure of the water. At the same time, that is to say, on the opening of valve (i, the inner end of member 15 iinpinges tightly against the washer 14, thereby making a water-tight joint simultaneously with the opening of the valve. Then the member l5 is disengaged from the member l, the valve 6 will automatically seat itself, due to the pressure of the water behind it.

It will thus be seen that my hydrant is easily operated, is positive., has few parts, and will not readily get out of order.

A suitable cap 24', adapted to be screwed or otherwise fastened on the end of the member l, may be provided to close the outlet-end of the hydrant when the same is not in use.

In Fig. 7 I have shown a slight-ly modified form of my hydrant. In this modification, the tubular member l is shown vertically disposed instead of horizontally disposed, as shown in Figs. l and 2, but the internal arrangement of parts is the same in all respects as heretofore described, except that, instead of having a detachable valve-opening and coupling-member l5, as before described, a nozzle-member 25 having its inner end screw-threaded, as at 26, is shown, which nozzle-member is adapted to be held against withdrawal from said tubular member l by a set-screw 27. Thus, when the nozzle-member 25 is screwed inwardly, the valve 6 will be opened, as hereinbefore described; when the nozzle-member 25 is unscrewed outwardly, contact with valve-stem 7 is removed and the valve closes. If desired, the outer end of the nozzle-member 25 may be screw-threaded or otherwise arranged for the attachment of a hose or other pipe.

It will be understood that my hydrant and its several parts may be made of any size desired, depending upon the use to which the hydrant is to be put, and that minor changes in the arrangement, construction, and combination of the several parts of my hydrant may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
